Lenen Puma No. 94,803, daad september 14, 1869,

To all whom it may concern:

Be it known' that we, JOHN C. WILSON, ADAM WALKER, and JOHN FOSTER, all of the city, county, and State of New York, have. invented a new and useful Improvement in Clipping-Shears, for clipping or shearing the hair of horses and other animals; and do hereby declare that the following is a general description thereof', reference being had to the accompanying drawings, making part of this specication, of which- Figure l is a top view of our improved clipping\ shears;

Figure 2, a longitudinal section of same;

Figure 3, an under side view of the upper serrated cutter, showing heel-spring, circular opening for passing the said plate over the lever-handle, with recesses for reception of double-toothed lever; and

Figure 4, a sectional view of said upper serrated cutter, showing heel-spring and set-screw.

The nature of our invention consists' in constructing a clipping-shears with a double-'toothed lever for perat-ing the upper or movable serrated cutter, and the said cutter' with a spring heel-plate and set-screw, for closing the cutters as they wear fromA use or .from sharpening; also, in providing said movable cutter with an opening iu thel centre for passing thecutter over the lever-handle, when the cutter-blades may require sharpening, while the lever lWhichoperates said cutter is firmly attached to the lower cutter-blade; and also in connecting the cutting-blades near their serrated edges by means of slab-sided screw-bolts, washer, and nuts, which will not work loose, while they allow the upper serrated cutter to slide freely back and forth on the lower or stationary serrated cutter.

In the said drawingsv A indicates the lower or. stationary serrated cutter, mounted with a handle, B.

C is the upper or movable serrated cutter attached to the stationary cutter by flattened orslab-sided bolts D, continuous washer or plate, E, and nuts F.

These bolts and nuts remain stationary and will not work loose, because of the bolts being slab-sided, while the upper cutter C, having slots c c, &c., slides freely back and forth.

G is the spring-heel plate, rmly secured to the upper cutter by livets h h and operated by a set-screw,

I, for the purpose of elevating the tail end of the y movable cutter, so as to adjust the serrated edges of the cutters in relation to each other, should they become worn from use or from sharpening. K K are the recesses in the said movable cutter for reception of the double-toothed lever; and L i4 the circular opening, which admits (on remov- .iug the bolts and nuts) of passing the movable cutter over the leverhandle, when it may be desired to sharpen the cutters, while the lever remains firmlyv attached to the stationary cutterl M is the double-toothed lever, of which N is the handle, said lever being firmly attached by a rivet, O, to the stationary cutter and provided with teeth, p p,

which play into corresponding recesses K K, in the.

movable cutter, by meansof which the movable cutter' is slid back and forth on the stationary cutter and the clipping-operation performed. f

We are aware that Letters Patent, No. 84,926, dated December 15,1868, were issued to us for au improvement -in clipping-shears; butwe have found from experience with this clipping-shears that it necessitated further improvements to render its performance .perfect, inasmuch as the heel of the movable cutter B, in

, its movements, wore a channel in the shank A of the stationary cutter, on which it rested, causing the cutters to spread apart, whichl defect was partially overcome for a time by bracing the plates together by the thumb set-screw L. But this operation retarded the movements 'of the sliding cutter, while the thumb set-screw itself worked loose, allowing the cutters to spread apart. Besides this, the wear on the single tooth D of the lever affected able cutter.

These defects in the original horse-clipper suggested to us our improvement, which'we find, from use of same, to'answer the desired purpose.

Having described our invention,

What we claim, and desire to secure by Letters Patent, is p The double-toothed lever M, spring-'heel plate Gr, set-screw I, circular opening L, bolts D,and plate E, constructed, arranged, and operating substantially as and for the purposesdescribed and Set forth.

In testimony whereof, we have hereunto set our signatures, this 9th day of August, A. D. 1869.
